Original application filed November 10, 1,913, Serial No. 799,724. Divided and this application led lFebruary 1 2, 191.4. Serial No. 815,995.

T o all lwhom it muy concern Be it known that I, VILLIAM S. TnErLn, A'residing at lVellsburg, in the county .of

Brooks and State of lest Virginia, a citizen of the United States, have 'invented or discovered certain new and useful Improvements in Glass-Working Machines, of which the following is a specificittion.'. y l

My invention relates to machines iof the illustrated and described-in my application, Serial No. 799,724, iiled Nov. 10, 1913, and the object of my invention is to simplify the'ygeneral construction and operation of such machines, and particularly of the machine' shownv in said application.

A morespeciic'object of my invention is 'to reduce to a minimum the number of valves and movable elements of these machines, effecting' with less vAs in my vpending application, l show glass blanks adapted to be subsetmentlyv blown into bottles, the blowing table being illustrated but forming 'no part fof my present` invention.

molds 9, is rotatably mounted,

chine, the valves and operating parts being shown, in section whereit is necessary for their complete understanding.

1n the several figures like numerals are used to designate like parts.

The motive power for substantially all the movable parts ofthe machine is 'fluid pressure, applied either directly or indirectly to such parts. Since compressed air is required for blowing the glass articles, it,

.rather than steam or other pressure fluid,

may be economically and advantageously used for operating the machine.

' lheseveral operating partsof the inachine may be conveniently classed under three heads, first, those having to do with the shears; second, the movement of the table; and third, the operation of the plunger. As the plunger operating mechanism shown herein is the same as that illustrated and described iii my pending application, it will be necessary to describe in detail only the shear and table-moving mechanism, and this will be done iii. the order named after first describing the general construction of the machine.

The complete machine is suitably mounted on a truck comprising wheels 1, side frames 2 and platform 3. At the left end ofthe platform, as seen in Fig. l., a rotatable blowing table 4, provided withmolds 5, is mounted; and a blower 6 is secured to a central rod 7 in position to register with the molds 5 as they are successively brought beneath it. As stated heretofore, my improvements are not illustrated as applied to the blowing table, so that further description of it is' At the right end of the plat- 8, provided with the table being sustained directly by ball bearings l0, as seen in Figs. Ll and 5. l

A. rod 1l extends through the center of the mold table 8, and a rod 12 is at the side thereof, both rods beiiigattaclied'to the platform 3 and sustaining at their outer end the plunger and its operating mechanism. The essential parts of the' plunger mechanism comprise ya cylinder 13, plunger rod 14 hay ing a former 15 at its 'lower end, and timing valve 1G, it being understood that the rod '14 is caused to reciprocate through the cyl-- inder 13. the former 15 entering successively each mold 9 and shaping the molten ginas previously placed therein. rlhe y shears 17 unnecessary. form 3 the mold table ice ' the V connected into a single structure .which is clamped to the rod 11 above the general plane of the tops of the molds 9.

Such is the general structural arrange-- ment of the machine. In its general operation a quantit)v of molten glassis fed to such mold i) as is then inunediately beneath the shears 17, which air to their operating mechanlsm, to cut from thev gathering tool a quantity of the glass. which then drops into the mold. The operation of the shears controls the further flow ot' compressed air to the end that thc mold table is advanced one station (that is, angular distance between adjacent molds) so that the lilled mold standsbenealh the plunger `and thereafter the plunger' rod 1lis moved downwardly, its former 15 shaping the glass within the mold.

Referring now to the shears, their construction. as well as that of mechanisimis best illustrated in l"igs.11,12, 13. Il and 15. The shear blades, which are rigid and therefore capable of withstanding tlie conditions ot' service. arepivoted by a pin 1h' to a plate 19. which is secured to ac vlinder easing 20. A piston rod 21 yextends through 'one end ofthe c vlinder 20 and aty its outer end is attached to a forked member 22. the ends of which are pivotally connected one to each outer side of the blades li'. '.l`he inner end of the rod 21 is provided with -a piston head 23. means beingprovided to eausf air to aeton opposite sides thereof to open and close the shears, as -will be presently described. I

,Xorniallvz the shears and their moving mechanism are in the positions indicated in the drawings. being thus ready toI Cut a quantity of glass from the gathering tool. 'lo cause the shears to operate, I provide a single valve comprising a casing 2l having a valve seat therein. and a movable stem 25 provided with a valve plug'held yieldingly in closed valve4 position by means of a spring 2o. the easing. on opposite sides of the valve seat. being connected to the live air suppl)r by pipes 2T and 2T". and tothe rear end of the cylinder 20 by pipe 28. 'lhe stein .25 may be lowered to permitair to flow to the cylinder il() b v meansoic a lever 29,- pivoted to thenpper portion of the casing '2l-.land bearing upon the outer vend of the valve stem 25, the arrangement being such that the lever 29 ma)v be lowered b v the panty in the hands ot' the gatherer after a suiiieient amount of glass has flowed from it. The table-turning mechax'iism is also operated by air'which is let thereto after the shears have cut the glass. For this purpose a compound plunger' valve is used, it prelferably being secured to the top of the shear cylinder 20, and compi-15mg a casing 30 and are caused, byLletting live` theirv operating and held yieldingly a two-position valve rod 31, provided with four collars 32, 33, 34and 35, the, rod alwa'ys being in its lowermost position immediately preceding each operation of the shears. The lower part of thev casing 30 communicates .through port 40 with the cylinder 20. As

will best be seen .in Fig. 15, this casing has leading from it pipes 36,37 and 38, and a.

valve-controlled outlet 39, the purpose of 'the tablermovingmeans which are thus set in motion. y The exhaust from the cylinder 20 and the upper end of the ,casing 30 escapes through pipes 38, 82 and 80 to a cylinder (i2 provided with a free outlet port 90.

let'erring`- now' to the table-turning' mechanism, it may be best seenin Figs. l and-10 inclusive and 15. Asis usual lin ma.- chi'nes of this character, the table is locked after each intermittentadvance of one station. The complete table-moving mechanism therefore comprises means for unlocking the, table. and means for moving it, In order to lock the table, a series of detents il, corresponding in number to the intended trading therefrom, such ,detentsbeing adapted to be engaged by means of a movable finger l2, engaging position by means of a spring 43. The finger l2 is mounted in a casing 44, pivoted at its outer end to the platform 3, by a spring 4 5, toward the advance of each approaching detentril. Adj ustable yset screws 46 limit the movement of the finger casing ll inthe direction-'ofv rot-ation of the table 8, the arrangement of these several locking parts being such that, when a detent l1 strikes the finger 42,' vthe movement of the table will 'be retarded' under the i be inall)y stopped at its exact intended position when the casing lvl strikes the screws 46.

Such being the table locking means, its

held yieldingly in -detentaction of the spring l5,and willv '1 movement is effected buv-means of a piston provided with a head 48 movable' through a fixed cylinder 49, the outer en'd of .the rod 4T being providedy with atable-en- 1' chine, as far as my present invention is concerned, consists ot" opening the shears 17 andell'ecting'the return stroke of the piston rod To such end a pipe SOleads from the, eylinderZ. near the top thereof and extends to the timing valve 1G. A branch S2 of'said pipe 80 entends to the shear cylinder 20,'and. by pipe'b. to the valve easing 30.

It willv ,bel seen that. by such eonstruetiony. when the piston head (il vis lowered, live air will flow Tfrom the source ot' supply through vinder G2, pipe H() directly to the Atiming valve 1G, and through pipe S2, lemlin'g'fron'i pipe 80, to the shear cylinder 20, and also through pipe ?'.`lea 'ling from pipe to the valve casing 230. ly means of the, live air, thus` led to `these several parts. the timing valve 'Si will operate as illustrated and described in my heretofore.mentioned pending application: the shear piston head 22 lwill move to open 'the shears. the exhaust air fat the rear thereof escaping' through`v pipe 2S and a liv-pass H-l in the siem 25 of the starting val ve: and the valve rodA 81 will he moved downwardly. the exhaust air at the bottom lhereol'l escaping through port 4() and through a port S5 in the cylinder Q0. The 'valve rod 91 being thus moved to the position shownin the drawings, live air will flow-'from the source ot' supply A through pipeQ'), 2T, casing il() between collars 325 and 34,' pipe ST'and check valve 73 to the -cylinderslflacausing the piston head 4S t move to'the positlon indicated. In tlli.y movement of the head 4H, the exhaust air escapes v"from the cylinder 4i) through pipe 36, casing- 30 between the collars 32 and 3?), and port 86 in such casing,

. '.lhe complete operation of the machine, oniitting ifor'the most part the enumeration of 'the' pipes through which airis caused to How, is 'as follows: The gatherer. after a sulicient quantity ot molten glass has flowed froni liis'puntv, depresses the lever through theA valve 2l, 25 to the shear cyl- 'index' 20, which air moves the. piston head Q Qto operate'thc shears 17. 'As the head 22 moves Aforwardit uncovers the port 4() of cylinder 20 leading 'to the valve casing y30 so that air enters such casing and nieves the valve stem 31 upwardly"4 through it.y Live air then passes through the casing tlrandl pipe 36 tothe cylinder 49 causing A Ies As the rod47 nears theend of its stroke,

the. abutment 66, through linger 67 andy rod (38, moves the valve (59 so that air Hows to thecylinder ($2 causing' the piston head (il to'move downwardly and release the pin 50 from its engagement with the table. When the piston head ll is in its lowered position live air flows through the cylinder 62 by pipe S() to the timing valve 16, and b v pipe 82 (a branch of pipe S0) to the shear cylinder 20 and valve casing 30, thus calls# ing the sh lars to open and the valve rod 231 to"move to its 'lower position. The operation ot' the timing valve 1G, as described in 111).',A pending a|'i|ili .'ation completes the full cycle ot' operation of the machine.
